In Windows Vista, Microsoft introduced a new feature named "auto tuning" for TCP/IP. In theory, "auto tuning" can be adjusted and optimized based on network application conditions, this increases the network transmission rate. In the default settings of Windows Vista, "auto tuning" is automatically enabled. However, in practical applications, "auto tuning" sometimes does not play the expected effect, especially when the network adapter uses a third-party driver, it may even greatly reduce the
